Abstract
Procedure for obtaining compounds derived from pyridine with formula I, where X is N or CH triradical, R<1> is a hydrogen, methoxy, difluoromethoxy 2,2,2-trifluoroethoxy, isopropyloxy, 2-methylpropyloxy or cyclopropylmethyloxy radical, R<2> and R<3> are independently a hydrogen, methyl or methoxy radical, and R<4> is a 2,2,2-trifluoroethyl, ethyl, isopropyl, methyl or 3-methoxypropile radical, excepting the case in which simultaneously: X is -CH=, R<1> is MeO-, and R<2>, R<3> and R<4> are Me the procedure consists of at least 7 steps, the first being the N-oxidation of a methylpiridine with H2O2 and a catalyst, and the last an S-oxidation of a thioether with a peracid or with H2O2, a base and a catalyst.
